Nonlinear Control Algorithms for Dynamic Shake Table Tests

Overview

Shake table testing is a key technique to experimentally investigate the responses of structures under different earthquake excitations. Due to the inherent nonlinearities of the tested structural systems and control-structure interaction (CSI) effects, it is difficult to regulate the shake table behavior using traditional linear control algorithms such as proportional-integral-derivative (PID). This research aims to investigate a series of nonlinear control algorithms such as backstepping control and adaptive control theories to enhance the control performance in shake table tests.
